Initial Messages work as you'd expect
Version 2.1
Did you also wonder why you need to place an On Incoming Message action at the beginning of your telegram chat level? It's because it catches and handles the initial message that started the new session. But why does it still do that if I already responded with a plain and simple Send Message ๐คจ? Well, it does not anymore 
adaptor:ex Version 2.1.0 comes with some bug fixes and a slight change to the "Default Level" behavior for messenger listeners.
